You can use Virtual Machine Manager (VMM) to manage your physical and virtualized network infrastructure. In VMM, the foundations of the network configuration are networks—the underlying logical networks and the VM networks—and switches. Switches can be configured as standard virtual switches, but this set of topics describes logical switches, which help you configure switch settings consistently across multiple hosts. To configure these network elements in VMM, use the following overviews and procedures :

You can use Virtual Machine Manager (VMM) to manage your physical and virtualized network infrastructure. Logical networks form the foundation of your network configuration in VMM. You create and name logical networks based on the function they serve in your environment, for example, the “Management,” “Cluster,” “Storage,” or “Tenant” networks. Within each logical network, you create one or more network sites that specify IP subnets, virtual local area networks (VLANs), or subnet/VLAN pairs that represent your environment.

In a logical network, you can provide static IP addressing by creating static IP address pools for the logical network. Dynamic Host Configuration Protocol (DHCP) is also an option.

In Virtual Machine Manager (VMM), after you complete the planning described in Overview: plan logical networks, network sites, and IP address pools in VMM, you can plan your VM networks. Use this table for more information:

You can support multiple tenants (also called clients or customers) with their own networks, isolated from the networks of others, by using VM networks configured for network virtualization.

Direct access to the logical network (“no isolation”): described in this table

A VM network can provide direct access to a logical network. No planning is needed, other than to identify the logical network to give access to. This is the type of VM network typically used for management networks (for example, the network used for managing a host).

In Virtual Machine Manager (VMM), you can use logical switches (and the port profiles inside them) to help you configure switch settings consistently across multiple hosts. A logical switch is like a template for a virtual switch—it acts as a container for the switch settings and capabilities that you want to use. Instead of configuring switch settings individually for each network adapter, you can specify settings and capabilities in a logical switch, and then use the logical switch to apply those settings consistently across network adapters on multiple hosts.
